Only Forward by Micheal Smith.

That's pretty wild. It's a sort of mystery/sci fi hybrid. The neighborhoods alone in the city that the detective lives in are very odd. Like the "silent neighborhood" where you have to wear quite shoes and all noise is forbidden save one hour a day where you can go into a little room and scream all you want.

Or the "color neighborhood" where the walls will change color to compliment the clothes you are wearing as you pass.

It's a bit old, so it's really cheap on amazon.
